#7 Error on first time access site

[devcovato]

Hi,

Before I download a last version, but I obtain an
error when access first time to the site.
Some descriptions error are in italian.

This is a stack error:

[InvalidCastException: Cast specificato non valido.]
ManagedFusion.Data.SqlServer.Sites.SelectAll() +393

[Exception: Sites::SelectAll::Error occured.]
ManagedFusion.Data.SqlServer.Sites.SelectAll() +654
ManagedFusion.Data.SqlServer.SqlServerProvider.get_Sites() +80
ManagedFusion.Types.SiteInfo.get_Current() +794
ManagedFusion.PortalModule.Application_BeginRequest(Object sender, EventArgs e) +218
System.Web.SyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() +92
System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) +64

So, after that I decided to download code via SVN but
I discover that the code is different from dowloaded code. Why? Which I use?

Thanks in advance,
devcovato
